摘　　要：阐述了CFRP布约束混凝土柱的受力原理及破坏形态,探讨了CFRP布约束混凝土柱的侧向约束机理,进行了在混凝土等级不同、加固量不同条件下矩形柱与圆弧化处理柱的性能对比,并分析了圆弧化处理截面优于矩形倒角截面的原因,提出了将来CFRP布约束混凝土矩形柱的圆弧化处理建议。Elaborated the CFRP cloth restraint concrete column stress principle and the destruction shapes has discussed the CFRP cloth restraint concrete column sidewise restraint mechanism.And made a performance contrast between rectangular column and circular arc processing column,in the concretes rank different and under reinforcement quantity dissimilar condition,analyzed the reason why the circular arc processing section to surpass the rectangular bevel edge section,put forward the future CFRP cloth restraint concretes rectangle column＇s circular arc processing proposal.
